So I read probably the most in-depth discussion on stance widths by Kyle Schmidt on Humanoids website. It is a great read and they also have a stance calculator that is more advanced than other that I have seen.

I've Always ridden 24-26" probably since about 2000 or so, depending on available stance options. The only exception was in 2001 when I tried the super-wide thing for about a week and also tore an ACL. I ran my data through the Humanoid calculator and it came back as 23". Additionally, the weather has been poor this week and I had my boots off my board to fix the laces. Without reference, I put them on and stood comfortably--High, low and midway to find what felt best. I marked the spots on the floor and then measured the space. I measured it at 23.25. I did it again a few hours later and it measured 23 even.
23" for someone my size doesn't look weird or like I am doing it just for the sake of having a skinny stance, but it is narrower than I have ever ridden (on a modern board).
What stance are width is everyone riding? Include your height, board size and if you consider your self knock-kneed, straight legged or bow-legged.
I'm 69.5 inches tall, I ride a 140 William and my legs are pretty straight.
My Current stance is 25".
